Here are a couple of clips from other websites about sulfates and why they are bad for our hair:

“Sulfates are compounds derived from sulfuric acid which are found in most commercial shampoos. Companies add these harmful components so their products will create pretty suds when applied and lathered into your hair. Unfortunately, those same sulfates strip away vital natural oils that keep your hair healthy and strong. The result? Dry, brittle strands that appear dull and break easily. Most stylists today will tell you that a good sulfate-free shampoo is the first step to longer, healthier-looking hair.” Learn more Here

“Sulfates are a group of detergents or surfactants that are used in countless consumer goods today. The most commonly used sulfates are sodium lauryl sulfate (SLS) and sodium laureth sulfate (SLES). These corrosive cleaning agents started off as an industrial strength cleaning additive since they easily cut through heavily soiled surfaces.” Learn more Here
